I was wondering if you'd put a comma after direction phrases. For example: "Right above him, the shadow exploded into thin, black strands." Or possibly, another example: "To the right of him, it exploded into thin, black strands." Would the commas be correct these examples? Thank you for the help.
yes... just because it's an modifying, adverbial phrase, that tells us 'where' it 'exploded'... same would apply to a phrase that tells us 'how, when, etc.'...
Yes you place a comma before prepositional phrases, which these are examples of. You also place a comma before all types of phrases and instroductory clauses. Even an introductory adverb. Lovingly, she blah blah. There are exceptions, but it is always okay to place a comma before these things.
